public void serializeWithType(Object value, JsonGenerator gen, SerializerProvider ctxt, TypeSerializer typeSer) throws IOException

Overrides com.fasterxml.jackson.databind.ser.std.ToEmptyObjectSerializer.serializeWithType.

Doc from com.fasterxml.jackson.databind.JsonSerializer.serializeWithType.

Method that can be called to ask implementation to serialize values of type this serializer handles, using specified type serializer for embedding necessary type information.

Default implementation will throw UnsupportedOperationException to indicate that proper type handling needs to be implemented.

For simple datatypes written as a single scalar value (JSON String, Number, Boolean), implementation would look like: 

  // note: method to call depends on whether this type is serialized as JSON scalar, object or Array!
  typeSer.writeTypePrefixForScalar(value, gen);
  serialize(value, gen, provider);
  typeSer.writeTypeSuffixForScalar(value, gen);
and implementations for type serialized as JSON Arrays or Objects would differ slightly, as START-ARRAY/END-ARRAY and START-OBJECT/END-OBJECT pairs need to be properly handled with respect to serializing of contents.
Parameters
value:Object

Value to serialize; can not be null.

gen:JsonGenerator

Generator used to output resulting Json content

ctxt:SerializerProvider

Provider that can be used to get serializers for serializing Objects value contains, if any.

typeSer:TypeSerializer

Type serializer to use for including type information
